Cast Irons types and composition - China Foundry

Cast irons come in a variety of types however these cannot be specified by chemical composition because of the similarities between the types. The table given below shows the distinctive composition ranges for the most frequently determined elements in the 5 generic types of cast iron.

Cast irons

Cast Irons Angel Yescas-Gonzalez and H. K. D. H. Bhadeshia Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent CE of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as

Malleable cast iron - Total Materia

Malleable cast iron is a heat-treated iron-carbon alloy which solidifies in the as-cast condition with a graphite-free structure i.e. the total carbon content is present in the cementite form Fe3C . Two groups of malleable cast iron are specified differentiated by

Cast Iron Types Advantages Disadvantages Uses

Cast iron is a ferrous alloy which has more than 2% carbon in it. Though it can have any percentage of carbon between 2% to 6.67% but practically it is in between 2% to 4% only. It has got its name due to its excellent casting qualities. It is hard and brittle. There

The Material Composition of Cast Iron

Cast-Iron: Manufacture Composition Types Properties

Cast-Iron: The composition of this variety of cast-iron is so adjusted that it becomes malleable. It is done by extracting a portion of carbon from cast- iron which makes it less brittle than cast-iron. The process of manufacturing is known as In this

Difference Between Mild Steel vs Cast-iron vs Wrought Iron

Cast iron contains about 2 to 4 % of carbon. Also it contains various impurities such as manganese phosphorus silicon and Sulphur. The manganese makes cast-iron brittle and hard. Therefore its proportion should be kept below 0.75 %. The phosphorus

Cast Iron Types Metal Casting Resources

The primary difference in production between wrought iron and cast iron is that cast iron is not worked with hammers and tools. There are also differences in composition—cast iron contains 2–4% carbon and other alloys and 1–3% of silicon which improves the casting performance of the molten metal.

Corrosion of Cast Irons – IspatGuru

Ductile Cast Iron: Process Composition Differences

Cast iron costs about 30 – 35% lower than cast steel. It also has a better wear resistance and vibration damping as compared to cast steel. In addition because of a larger concentration of free carbon and higher silicon content graphitic gray and ductile cast iron has the greatest fluidity and the least shrinkage of any ferrous metal.

Cast iron - Wikipedia

OverviewTypesProductionHistorySee alsoFurther readingExternal linksCast iron's properties are changed by adding various alloying elements or alloyants. Next to carbon silicon is the most important alloyant because it forces carbon out of solution. A low percentage of silicon allows carbon to remain in solution forming iron carbide and the production of white cast iron. A high percentage of silicon forces carbon out of solution forming graphite and the production of grey cast iron.
